Honeywell Home 4191WA

The Honeywell Home 4191WA is a steel door adapter for the 4191SN-WH. It is a 3/4" (19mm) Adapter. The idea is to allow the compatible 3/8" 4191SN-WH contact to be mounted into a 3/4" hole in the steel door. It is suggested to use the 4191WA when mounting the 4191SN-WH into a steel door.

The Honeywell Home 4191WA allows proper installation of the 4191SN-WH wireless door and window sensor on metal doors and frames. Standard recessed contacts rely on consistent magnetic alignment to detect open and closed states, but steel doors can interfere with the magnetic field. This adapter helps maintain proper spacing and alignment so the sensor can function reliably in these applications.

The 4191WA is used specifically with the Honeywell 4191SN-WH, which is a recessed wireless door and window contact. When installing that sensor in a metal door or frame, the adapter creates the correct separation between the sensor body and magnet. This helps prevent signal loss or inconsistent operation that can occur when the magnet is too close to metal surfaces.

The adapter is installed within the drilled hole used for the recessed sensor, allowing the sensor and magnet to be properly positioned inside the door and frame. It is designed to fit cleanly with the sensor housing, maintaining a discreet appearance while improving performance. This makes it a practical solution for installations where aesthetics and reliability are both important.

The Honeywell Home 4191WA is a simple but important accessory that helps expand installation options for recessed contacts. It allows the 4191SN-WH to be used in applications where metal construction would otherwise limit performance, making it a useful addition to many security sensor installations.
